TO ALL WHOM IT MAY CONCERN:

Be it known that I, FREDRICK J. GRACE, of Fort Lee, in the county of Bergen, and State of New'd'ersey, i

have invented and made a. certain new and useful Improvement in Printing Presses; and I do hereby declare `the following to be a. full, clear., and exact description of the same, reference being had to the annexed drawing, vmaking part of this specification, wherein- Figure 1 is an elevation of said press at the delivery end; and

Figure 2 is a vertical section transversely of the type cylinder.

Similar marks of reference denote the same parts.

The object of my invention is to print labels, telegraphic blanks, and other matter requiring Ifrequent repetition. This I eect by a. continuously revolving cylinder, carrying stereotypes or electrotypes with spaces between them. The paper is drawn from a. roll and printed upon against an impression cylinder, and as each impression is compietcd the movement of the paper is arrested by the impression roller being forced back out of 'contact with the printing cylinder, and during the pause the strip of paper is cut offbetween the two impressions by means of a. shear-eporated-ztt the proper time by..a connection with the printing cylinder.

In the drawing, a is a. suitable framework sustaining the shaft, b, that is driven by gearing, c, to the iiywheel, e, rotated `by a crank-handle or otherwise. f is a printing cylinder formed of heads set on the shaft 5, and adapted to the reception of printing plates, 'g g, that may be 'stereotypes or electrotypes cast or bent to the segment of a cylinder corresponding to the headsf. The inking of the type is effected by the rollers, c'z'and h, between which are the working and distributing rollers, k k. Z is the ink trough, in which is a. roller, n, that supplies a regulated amount of inl: to the working roller, m. O'ne end of the rollers 1,' z' and h, or a separate hub on each one, is to travel in contact with the periphery of the cylinder head f, so as to keep the inking and working rollers always in motion. The paper passes from a roll, o, suitably located, over the impression roller, p, and thence to the shears, composed of the standing blade, r, andmoving blade, s, mounted upon the adjustable bed, t, so as to be moved to the proper position for cutting off the paper between the respective impressions during the pause in the movement of the paper between one impression of the types and the next. The pause in the movement of the paper is produced by depressing the roller p againstpthe action of the springs, q, shown by dotted lines in iig. 2, and thereby preventing the pressure and movement of the paper between the surfaces of p and f. I employ the levers, u u, en the rock-shaft, v, said levers being adjustable thereon so as to be outside of the headsff, in order that the cams, vl, ou said leversu, may be acted upon by the pins, a: x, and cause the under sides of the levers u u to press upon the surface of the roller p, and move the roller down out of oontact with the cylinder` heads f, and thereby stop the paper; and I actuate the shearl t by a prolongation of the levers u, or one of thom, so that the motion given to the shear to cut off the papertakes place at the time that the pause occurs between the printing.

What I claim, and desire to secure by Letters Patent, is

l 1. I claim the impression roller p, mounted upon springs in combination with the levers u' u, for moving the rollerp back to prevent the paper being rooted@v as set forth.

I claim the adjustable .shear r s, in combination with the actuating lever u, and pins and cams :v and v1, as and for the purposes speciiied. y

In witness whereof I have hereunto set my signature this 10th day of'August, 1866.

FREDERICK J GRACE.
